v-cloak does not work in vue.js? - vue.js

There is a div in my page that for show the error message.When I refresh the page,it will appear for a while then it disappear. I added v-cloak but it doesn't work.
this is the code, showErrorMsg is false
<div v-cloak v-show="showErrorMsg" style="z-index:100" class="h5_tips tips_error">
<i></i>
<p v-text="errorMsg"></p>
</div>
How to fix this?

Just include this code to your css file
[v-cloak] { display:none; }
http://vuejs.org/api/#v-cloak
Usage example:
<div class="xpto" v-cloak>
Hello
</div>
This directive will remain on the element until the associated Vue
instance finishes compilation. Combined with CSS rules such as
[v-cloak] { display: none }, this directive can be used to hide
un-compiled mustache bindings until the Vue instance is ready.
http://vuejs.org/api/#v-cloak

I faced the same issue, and it was due to a conflicting display property on my div. To solve it, I used the !important flag on the [v-cloak] as:
[v-cloak] {
display: none !important;
}
.my-class {
display: table-cell;
}

Vue.js - 2.3.4, I added the v-cloak on the app container, adding this on the parent container, I find your not repeating the code keeping it DRY.
HTML:
<div id="app" v-cloak>
Anything inside gets the v-cloak
</div>
CSS:
[v-cloak] {
display:none;
}
Codepen Example:
https://codepen.io/Frontend/pen/RjoKQm

I fixed this problem by rewriting the CSS and adding a class in the CSS file
CSS:
[v-cloak] .v-cloak--hidden{
display: none;
}
HTML:
<div v-show="showErrorMsg" style="z-index:100" class="h5_tips tips_error v-cloak--hidden">
<i></i>
<p v-text="errorMsg"></p>
</div>

If you are using CDN to get Vue and using Bootstrap CSS then the reason might be you are loading the Bootstrap CSS in the bottom of the body tag, moving it back to the head tag worked for me. Make sure that you keep that vueJS file in the button as it is.
<HTML>
<head>
All link and script tag here
</head>
<body>
<div id='app' v-cloak>
{{ something }}
</div>
<script src="app.js"></script>
</body>

I have a scenario where I've got a search form and below, the results with a v-if block, waiting for submit.
I changed the v-if to v-show, that seemed to help. I tried the v-cloak--hidden class but didn't work either (v-cloak is already styled to display: none). What did work apparently was to set the data results container display style to none and then when submitting the form (in the processForm method), setting the display to block and show all the results.
processForm() {
// reset page number on new search
document.getElementById("data-container").style.display="block"
this.pageNumber = 1;
this.remoteRequest();
},
Without that change, on a full page refresh I could still see the moustaches coming up. Here the full HTML page, simplified.
<div id="app" v-cloak>
<main class="main-section">
<form method="POST" class="p-4 text-center" #submit.prevent="processForm">
<button type="submit" name="button" class="btn btn-primary">
Find
</button>
</form>
<!-- Results -->
<div id="data-container" class="container-fluid pt-2 pb-4" style="display:none">
<div class="row">
<div class="col">
<div id="recordsContainer" v-show="totalInScreen > 0">
<div class="card mt-5" v-for="(result, index) in results" :id="'itm-'+index" :key="result.id">
<div class="card-body">
<div class="row">
<div class="col">
<h2 class="doctor-name">{{ result.doct_name }}</h2>
<h2 class="doctor-bio">Bio</h2>
<p>{{result.doct_bio}}</p>
</div>
</div>
</div>
</div>
</div>
</div>
</div>
</div>
</main>
</div>

Unfortunately the above 2 answers didn't work for me as the problem was something else. Since this questions pops up #1 on Google, I thought I'd share my solution.
If you've defined a display css rule somewhere that's more specific, it will break the v-cloak functionality. However! Do not despair - simply copy this into your CSS file and it will work!
[v-cloak] .v-cloak--block {
display: block!important;
}
[v-cloak] .v-cloak--inline {
display: inline!important;
}
[v-cloak] .v-cloak--inlineBlock {
display: inline-block!important;
}
[v-cloak] .v-cloak--hidden {
display: none!important;
}
[v-cloak] .v-cloak--invisible {
visibility: hidden!important;
}
.v-cloak--block,
.v-cloak--inline,
.v-cloak--inlineBlock {
display: none!important;
}

Bootstrap, two responsive iframes, next to each other

I would like to have a Twitch player with chat on my site. I need it to be responsive. I am working with Bootstrap.
I have this code
HTML:
<div class="container-fluid">
<div class="row">
<div class="col-md-8 col-md-offset-1 nopadding">
<div id="player">
<div class="embed-responsive embed-responsive-16by9">
<iframe class="player" src="https://player.twitch.tv/?volume=1&channel=example&autoplay=false" style="border: 0px; top:0px;" allowfullscreen></iframe>
</div>
</div>
</div>
<div class="col-md-2 nopadding">
<div id="chat">
<div class="embed-responsive embed-responsive-16by9">
<iframe class="chat" src="https://www.twitch.tv/example/chat?popout=" style="border: 0px;"></iframe>
</div>
</div>
</div>
<div class="col-md-offset-1"></div>
</div>
CSS:
.nopadding {
padding: 0 !important; }
I am using this CSS to remove the padding from grid, I need to have player and chat next to each other, without padding.
The problem is that the chat is to small, exactly the height is too small. I can set the height in css, but this height won't change with the player's height. How can I fix that?
You can do this by setting the chat wrapper to absolute and then setting the iframe inside of it to have a width and height of 100% and position the chat-wrapper to left of 50% and give the row that it is all wrapped in a class and a position of relatve. Then at smaller screens you can position the chat wrapper to relative and left of 0 so that it will stack below the player when you get to mobile widths. Here is the markup I used. Also in the example I use col-sm but you can change it to col-md I just used sm because its easier to view in the fiddle demo.
Here is a fiddle demo drag the output screen larger and smaller to see the results at different screen sizes Fiddle Demo
Html:
<div class="container-fluid">
<div class="row player-section">
<div class="col-sm-6 no-padding">
<div class="embed-responsive embed-responsive-16by9">
<iframe class="player" src="https://player.twitch.tv/?volume=1&channel=example&autoplay=false" allowfullscreen></iframe>
</div>
</div>
<div class="chat-wrapper">
<iframe class="chat" src="https://www.twitch.tv/example/chat?popout="></iframe>
</div>
</div>
</div>
Css:
.no-padding{
padding:0;
}
iframe{
border:none;
}
.player-section{
position:relative;
}
.chat-wrapper{
position:absolute;
left:50%;top:0;right:0;bottom:0;
}
.chat-wrapper iframe{
width:100%;
height:100%;
}
#media screen and (max-width:767px){
.chat-wrapper{position:relative;height:300px;left:0;}
}
Another option is to create you own custom aspect ratios, as described in this blog.
If for example you want to show a pdf (A4 size) in your webpage, you can add the following to your style sheet:
.embed-responsive-210by297 {
padding-bottom: 141.42%;
}
Now you can add your custom stylesheet to your iframe:
<div class="embed-responsive embed-responsive-210by297">
<iframe src="..."></iframe>
</div>
By customising the aspect ratio of the different iframes, you can align the heights of all iframes to match mutually. Another advantage is that you follow the bootstrap philosophy.

Bootstrap 3 Carousel full screen flicker

I'm a beginner for web front-end design, using bootstrap to make a project prototype.
I want to do a product like this website
The features I want is
* expand carousel to full screen when visiting the website and then can scroll down to another div element.
I found this similar solution, but unfortunately it uses Carousel as the whole background.
To get the effect I want, I check the javascript src code and edit it.
modify this line (Shown on JSFIDDLE line 13 )
$('.carousel .item').css({'position': 'fixed', 'width': '100%', 'height': '100%'});
into this line (Shown on JSFIDDLE line 13 )
$('.carousel .item').css({'position': 'relative', 'width': $(window).outerWidth(), 'height': $(window).outerHeight()});
Yep, finally get the effect I want!! However, when the photo transition, a unexpected flicker appear, seems the photo is not at right location at first, then go to its right place immediately.
It's annoying when I see the content inside div below, like 1info or 2info.
here is the jsfiddle demo example for the issue.
I tried to use the solution like set z-index, but fail...
Can someone help me to solve this annoying problem? Thanks a lot!!
Here's a flicker-free version without any plugins:
HTML:
<div id="myCarousel" class="carousel slide" data-ride="carousel">
<div class="carousel-inner">
<div class="item active">
<div id="slide1" class="fill">
<div class=" carousel-caption">
<h1>1</h1>
</div>
</div>
</div>
<div class="item">
<div id="slide2" class="fill">
<div class=" carousel-caption" >
<h1>2</h1>
</div>
</div>
</div>
<div class="item">
<div id="slide3" class="fill">
<div class=" carousel-caption" >
<h1>3</h1>
</div>
</div>
</div>
</div>
</div>
CSS:
html, body {
height: 100%;
}
.carousel, .item, .active {
height: 100%;
}
.carousel-inner {
height: 100%;
}
.fill {
width: 100%;
height: 100%;
background-position: center;
background-size: cover;
}
#slide1 {
background-image: url('http://stylonica.com/wp-content/uploads/2014/03/Cute-Dog-Wallpaper.jpg');
}
#slide2 {
background-image: url('http://hdwallimg.com/wp-content/uploads/2014/02/White-Dog-Running-Wallpaper-HD.jpg');
}
#slide3 {
background-image: url('http://www.petfinder.com/wp-content/uploads/2012/11/122163343-conditioning-dog-loud-noises-632x475.jpg');
}
No additional javascript required, just make sure that the jquery and bootstrap.js files are linked in your page.

Twitter Bootstrap 3: How to center a block

It seems to me that the class center-block is missing from the bootstrap 3 style sheets. Am I missing something?
Its usage is described here, http://getbootstrap.com/css/#helper-classes-center
It's new in the Bootstrap 3.0.1 release, so make sure you have the latest (10/29)...
Demo: http://bootply.com/91632
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"/>
<div class="row">
<div class="center-block" style="width:200px;background-color:#ccc;">...</div>
</div>
It works far better this way (preserving responsiveness):
<!-- somewhere deep start -->
<div class="row">
<div class="center-block col-md-4" style="float: none; background-color: grey">
Hi there!
</div>
</div>
<!-- somewhere deep end -->
http://www.bootply.com/0L5rBI2taZ
You have to use style="width:value" with center block class
center-block can be found in bootstrap 3.0 in utilities.less on line 12
and mixins.less on line 39
You can use class .center-block in combination with style="width:400px;max-width:100%;" to preserve responsiveness.
Using .col-md-* class with .center-block will not work because of the float on .col-md-*.
center-block is bad idea as it covers a portion on your screen and you cannot click on your fields or buttons.
col-md-offset-? is better option.
Use col-md-offset-3 is better option if class is col-sm-6. Just change the number to center your block.
A few answers here seem incomplete. Here are several variations:
<style>
.box {
height: 200px;
width: 200px;
border: 4px solid gray;
}
</style>
<!-- This works: .container>.row>.center-block.box -->
<div class="container">
<div class="row">
<div class="center-block bg-primary box">This div is centered with .center-block</div>
</div>
</div>
<!-- This does not work -->
<div class="container">
<div class="row">
<div class="center-block bg-primary box col-xs-4">This div is centered with .center-block</div>
</div>
</div>
<!-- This is the hybrid solution from other answers:
.container>.row>.col-xs-6>.center-block.box
-->
<div class="container">
<div class="row">
<div class="col-xs-6 bg-info">
<div class="center-block bg-primary box">This div is centered with .center-block</div>
</div>
</div>
</div>
To make it work with col-* classes, you need to wrap the .center-block inside a .col-* class, but remember to either add another class that sets the width (.box in this case), or to alter the .center-block itself by giving it a width.
Check it out on bootply.

Dojo Tabs as Custom Widgets

I've created a number of widgets that are loaded as tab panes in a tabcontainer. Everything seems to work well, except I'm getting different results when using my custom widgets vs. creating everything in markup (tab content isn't taking up the whole page, 3rd party widgets aren't behaving properly, etc). This all leads me to think that I might not be creating my widgets correctly. The trick seems to be that they are not interpreted as contentpanes.
I am using dojo 1.3.2.
The following markup, for example, works great:
<body class="soria" style="overflow-y: hidden;">
<!-- Container for whole page -->
<div dojoType="dijit.layout.BorderContainer" design="headline" id="borderContainer" style="height:100%;width:100%;">
<!-- Header container -->
<div dojoType="dijit.layout.ContentPane" region="top">
Title
</div>
<!-- Left side -->
<!--<div dojoType="dijit.layout.ContentPane" region="left" id="addressContainer" splitter="true" style="width:100%; background-color: #F0F8FF;">-->
<div dojoType="dijit.layout.ContentPane" region="left" id="addressContainer" splitter="true">
<div style="text-align: center;">
<!-- address -->
<span id="addressInstructions">Address Contents</span>
</div>
</div>
<!-- Tabs -->
<div dojoType="dijit.layout.TabContainer" id="tabs" region="center" tabPosition="top">
<div dojoType="dijit.layout.ContentPane" id="tab1" title="map">
<p>Change map to:</p>
<div id="divMapList"></div>
<div style="padding: 10px 10px 10px 10px;">
<div id="divMap" dojoAttachPoint="divMap" style="width:300px;height:300px;border:1px solid #000;display:block;margin-left:auto;margin-right:auto;"></div>
</div>
</div>
<div dojoType="dijit.layout.ContentPane" id="tab2" title="other">
Some text in here.
</div>
</div>
</div>
</body>
Looking at the resulting HTML code, I can see that the tab itself has the following class: "dijitContentPane dijitTabPane dijitTabContainerTop-child dijitTabContainerTop-dijitContentPane dijitVisible".
Below is the HTML of one of my custom widgets:
<div>
<div style="text-align: center; padding: 5px 5px 5px 5px;">
<div>${i18nStrings.mapChangeMap}:</div>
<div dojoAttachPoint="divMapSelection"></div>
<div style="padding: 10px 10px 10px 10px;">
<div id="divMap" dojoAttachPoint="divMap" style="width:300px;height:300px;border:1px solid #000;display:block;margin-left:auto;margin-right:auto;"></div>
</div>
</div>
And here is part of the custom widget JS (I can provide more code if necessary):
dojo.declare("xxxx.Widget.Map", [dijit._Widget, dijit._Templated],
{
//Specify the path of the HTML file that sets the look of the widget
templatePath: dojo.moduleUrl("xxxx", "widget/templates/Map.html"),
//The strings used to populate standard text. Populated in postMixInProperties
i18nStrings: null,
//The widget's root div identifier. Value overwritten in postMixInProperties
id:"tabMap",
//The tab's title. Value overwritten in postMixInProperties
title: "",
//True to activate the tab. False otherwise.
activate: false,
//The map & current layer
map: null,
currentLayer: null,
//Sets up some basic properties
postMixInProperties: function() {
this.inherited(arguments);
var _1 = dojo.i18n.getLocalization("dijit", "loading", this.lang);
this.loadingMessage = dojo.string.substitute(this.loadingMessage, _1);
this.errorMessage = dojo.string.substitute(this.errorMessage, _1);
if (!this.href && this.srcNodeRef && this.srcNodeRef.innerHTML) {
this.isLoaded = true;
}
this.i18nStrings = dojo.i18n.getLocalization("IndyVIP","applicationStrings");
this.title = this.i18nStrings.mapTabTitle;
},
</div>
I am adding the widget to the container by creating the widget, then adding it as a child to the tabcontainer.
This results in the following class assigned to my tab: "dijitTabPane dijitTabContainerTop-child dijitVisible".
Does anyone know what I am doing wrong?
Thank you!
Emmster
UPDATE:
I have decided to try inheriting from dijit.layout.ContentPane & dijit._Templated. I am still having problems with that though, the main one being that if I add my widget to a TabContainer, I get the error "node is null" on line 4467 of dojo.js.uncompressed.js, but the tab seems to work just fine IF it's the active tab starting out. If I add the widget to a page that only contains the widget, it works fine without errors.
See the code below that gives me the expected results, but causes that one "node is null" error.

</div>
I very much appreciate all of your suggestions so far. I feel like I am missing something elementary, but I can't quite figure it out.

The issue I was having when inheriting from dijit.layout.ContentPane was that my top div in my widget template did not specify dojoAttachPoint="containerNode". Doing this took care of the "node is null" error I was getting.
I am still having issues with the map not behaving properly, but this seems related to the tab not being visible initially as dante hinted.
UPDATE:
The other error I was having (the map not acting as it should) was due to the widget's template HTML having items above the map in the widget HTML as in my first example above (map.html). In the second example I provided, I took that extra stuff out, and that fixes the problem.
Inheriting from the ContentPane and having dojoAttachPoint="containerNode" on the root node seems to be mandatory for the tabs. This helped me to resolve a similar issue.
